HAMMER-BUTT FLANGE FOR PIANO-ACTIONS.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed August 21, 1905, Serial No. 274,968.

To all whom, it may concern:

Be it known that I, IVILLIAM WV. MOCALL, acitizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Hammer-Butt Flanges for Piano-Actions; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a p art of this specification.

My invention relates to a hammer-butt flange for piano-actions, and has for its object to provide a device of the class described which will be simple and economical in construction and will afford great convenience in the assembling and removal of the ham mers in piano-actions.

Further objects of my invention are to provide the improved details of structure which will presently be fully described, and pointed out in the claim, reference being had to the accompanying drawings, forming part of this specification, in which like reference-numer als refer to like parts throughout the several views, and in which Figure l is a side elevation of a section of a hammer-rail provided with iny improved flange in which an ordinary hammer is mounted. Fig. 2 is a sectional view on the line 2 2, Fig. 1. Fig. 3 is a plan view of the blank from which a single flange is formed. Fig. 4 is a perspective of the flange formed from the blank shown in Fig. 3. Fig. 5 is a plan view of a blank from which a flange comprising a number of hammer-mounts may be formed. Fig. 6 is a perspective view of a flange formed from the blank shown in Fig. 5.

Referring more in detail to the drawings, 6 is a blank which may be formed in a suitable manner from a piece of sheet metal. At equal distances from the center of the blank are perforations 7, and from each end of the blank projects an ear 8, in one of which is a transverse groove 9. Blank 6 may be formed for a flange adapted to carry but one hammer, as shown in Fig. 3, or, if-so desired, a number of flange-sections may be formed in a single piece, in which case the metal is slotted to separate the blank into sections of a Width to accommodate a single hammer, said slot extending from the edge opposite groove 9 to a point near the longitudinal center of the blank in order that each flange-section may be operated independently of the others. When formed, the blank is bent on itself in the shape shown in Figs. 4 and 6, the lips 8 and the perforations 7 registering with each other, a wedgeshaped opening being left between the two members of the flange, said members being sprung together by pressure being brought to bear against the outer member.

I11 the operation of my device the flange is secured to the rail by a screw which passes through the perforations 7 and into the rail, as indicated in Fig. 1. The pin 10, which is fixed between the lips 11 of the hammerbutt, is slipped into the mouth formed by the lips 8 and seated in the groove 9. By tightening screw 12 the outer flange member is pressed inwardly against pin 10, holding said pin firmly in position. Pin 10 being loosely journaled in lips 11 the hammer is free to move when operated in the usual manner. When it is desired to remove a hammer, the screw 12 extending through that particular flange section is loosened, allowing the outer lip of that section to spring outwardly, releasing pin 10 and permitting the hammer to be lifted from its seat. In this manner a single hammer may be removed without disturbing the other parts. With my construction any number of sections may be formed in a single flange, as no matter how many sections are on the flanges the slots in the outer lip allow each section to be closed and opened independently of the other to remove the particular hammer desired.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

A device of the class described comprising a single piece of sheet metal bent upon itself, one member being solid to form a continuous back, and the forward member being slotted at intervals to form individual flange members, and means on said members for gripping the hammer-butt pins, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM W. MoCALL.
